Anstoss Ignition transformer UBZ 4 (12) TYPE1 07000581

The Anstoss UBZ 4 (12) TYPE1 ignition transformer (SKU 07000581) is designed for ignition systems in gas and liquid fuel burners. It operates at a supply voltage of 12 V with a power consumption of 1.5 W. The transformer has dimensions of 88 mm x 33 mm x 30 mm and can withstand ambient temperatures up to 120 °C. Its voltage tolerance is +20% / -30%, and it is suitable for applications within a temperature range of +14 to +248 °F. This component is used as a replacement part in boiler and burner equipment.

When selecting an ignition transformer of this type, ensure the primary voltage, secondary voltage and current, duty cycle, mounting style, terminal type, and ignition cable connector pattern match the original. Measure the physical dimensions and compare the voltage tolerance and ambient temperature limits to the application requirements. Inspect the high-voltage cable and electrode assembly for damage before installation, as a faulty cable can mimic transformer failure.

Common failure modes for ignition transformers include internal short circuits, open windings, or insulation breakdown, leading to weak or no spark at the ignition electrode. Equipment may fail to ignite, cycle on safety lockout, or produce intermittent ignition. Check the transformer's input voltage and output spark, and inspect the high-voltage cable for cracks or hardening that could cause spark leakage to ground.
